I have had my Macbook for a month or two now (bought in June, built in May) and I love it. I want to install Windows Vista on my Macbook in time for Warhammer Online that is due in September. I just installed 4GB ram sucessfully and want to use it all in Windows so I would like to use 64-bit. I have created a partition of 64GB for Windows (enough for the system and game I believe) but is there anything I need to download/burn in order for me to use 64-bit Windows? Such as a drivers disc etc... Thanks. Edit: Forgot to mention, I will be using a Windows Vista Ultimate 64-Bit with SP1 DVD. Is this ok? Does bootcamp work with a SP1 DVD?
